How much does it cost per year to maintain sealed pavers vs unsealed in Metro Vancouver?

Sealed pavers typically cost $200-400 per year to maintain for an average 400 sq ft patio in Metro Vancouver, while unsealed pavers cost $300-600 annually. The savings come from reduced moss treatment, less frequent joint sand replacement, and easier cleaning, though sealed pavers require periodic resealing every 3-5 years.

Sealed Paver Annual Maintenance Costs:

• Cleaning: $150-250 per year for professional pressure washing and moss treatment. Sealed pavers resist staining and organic growth, requiring less aggressive cleaning


• Joint sand replenishment: $100-200 every 4-5 years (averaged to $20-40 annually). Sealed surfaces protect polymeric sand from UV degradation and reduce washout during heavy rains


• Resealing: $1,500-3,500 every 3-5 years for 400 sq ft (averaged to $300-700 annually). This is the major cost difference — unsealed pavers don't require this expense


• Spot treatments: $50-100 per year for minor moss or weed control between major cleanings

Unsealed Paver Annual Maintenance Costs:

• Cleaning: $200-400 per year. Unsealed pavers in Metro Vancouver's humid climate develop moss, algae, and staining more readily, requiring more frequent and intensive cleaning


• Joint sand replacement: $150-300 every 2-3 years (averaged to $50-100 annually). Polymeric sand degrades faster without sealer protection, especially during Vancouver's October-to-March rainy season


• Moss and weed treatment: $150-200 per year. Unsealed pavers require more aggressive moss control products and more frequent applications


• Stain removal: $100-200 per year for oil stains, rust, efflorescence, and organic staining that penetrates unsealed concrete

Metro Vancouver Climate Factors:
The region's 1,200mm+ annual rainfall and 60-80% humidity levels create ideal conditions for moss, algae, and organic growth on paver surfaces. Sealed pavers resist moisture penetration and organic growth, reducing the frequency and intensity of cleaning required. However, even high-quality sealers degrade under Vancouver's persistent moisture and UV exposure, requiring reapplication every 3-5 years rather than the 5-8 years typical in drier climates.

The Real Cost Consideration:
While sealed pavers have lower annual maintenance costs, the periodic resealing expense ($1,500-3,500 every 3-5 years) often makes the total cost of ownership higher than unsealed pavers over a 10-15 year period. The decision should factor in convenience, appearance preferences, and how much hands-on maintenance you're willing to do. Sealed pavers stay cleaner longer and are easier to maintain, but unsealed pavers avoid the major resealing expense.

Practical Maintenance Tips:
For both sealed and unsealed pavers, the most cost-effective maintenance approach is annual spring cleaning (April-May) before the dry summer months, followed by joint sand inspection and moss treatment in early fall (September) before the rainy season begins. DIY pressure washing and polymeric sand replacement can cut maintenance costs by 50-70%, but sealer application should be left to professionals to avoid costly mistakes like hazing or poor adhesion.

When Professional Maintenance Makes Sense:
Properties with large paved areas (1,000+ sq ft), difficult access, or complex patterns benefit from professional maintenance contracts that bundle cleaning, joint sand replenishment, and sealing services. Many Metro Vancouver hardscape contractors offer annual maintenance packages for $0.75-1.50 per sq ft that include spring cleaning, fall preparation, and periodic resealing.
